FMeron is a frequency modulation (FM) synthesizer, controlled by the pitch and dynamics of your bass or guitar.

It starts with two pure sine wave oscillators which both track the frequency of the notes you play into it. One oscillator, called the Modulator, is not heard directly – instead it's used to modulate the frequency of the main oscillator, called the Carrier. This modulation transforms the pure sine tones into all kinds of clangs, bells, and intense electronic timbres.

The octave switch allows FMeron's synthesized tones to track one octave below, one octave above, or at the same pitch as your playing.

FMeron also includes an envelope generator, triggered by plucking the strings of your instrument. This envelope can be set to ramp up (Attack) or down (Decay) when triggered, and can either control the amount of FM (thus the intensity of the added harmonics over time) or the volume of the synthesizer voice, for slow-attack or percussive, plucky sounds.
